 # compatibility of two versions of GCC.

 # Each test has a main program that does nothing but call a function,
 # plus two additional source files that contain parts of a program that
 # rely on the ABI.  those source files are compiled into relocatable
 # object files with both compilers.  Executables are built using various
 # combinations of those object files, with the main program compiled
 # with the compiler under test and using that compiler's runtime support.

 # The including .exp file must define these callback procedures.
